Tadej Pogačar (Slovene pronunciation: [taˈdɛ́ːj pɔˈɡáːtʃaɾ] ; born 21 September 1998) is a Slovenian professional cyclist who currently rides for UCI WorldTeam UAE Team Emirates. He won the 2020 and 2021 editions of the Tour de France, winning three different jerseys during each Tour, a feat unseen in nearly four decades. Comfortable in time-trialing, one-day classic riding and grand-tour climbing, he has been compared to legendary all-round cyclists such as Eddy Merckx, Bernard Hinault and Fausto Coppi.

In 2019, he became the youngest cyclist to win a UCI World Tour race with the Tour of California win at the age of 20. Later in the year, in his debut Grand Tour, Pogačar won three stages of the Vuelta a España en route to an overall third-place finish and the young rider title. In both his Tour de France debut and the following year, he won three stages and the race overall, as well as the mountains and young-rider classifications, becoming the only rider to win these three classifications simultaneously. He is the first Slovenian winner, and, at the age of 21, the second-youngest winner after Henri Cornet, who won in 1904 at the age of 19. He is the first road cyclist in history to break the 6,000-point barrier in UCI World Ranking. He is a three time National Time Trial champion (2019, 2020, 2023).

He is the only rider who has worn the white jersey at the Tour de France 4 times overall and a record 75 days in total.

He has won three different one-day Monuments five times (Tour of Flanders and Liège–Bastogne–Liège once and Giro di Lombardia three times), Paris-Nice once and Tirreno–Adriatico on two occasions.

In 2021, he also made history when he became the first Tour de France winner to take an Olympic medal in the road race in the same year after he took bronze at the men's road race.

He is the current men's UCI road racing world No.1. He has been No.1 for a record total number of weeks and record number of consecutive weeks. He finished the 2021, 2022 and 2023 seasons as world No.1.
